Golden Goose Resources Ltd. has executed a Definitive Agreement with Valcheta Exploraciones S.A.S. to acquire up to a 100% interest in the Gran Esperanza Project, a high-grade epithermal gold-silver property located in Río Negro Province, Argentina. This acquisition represents a significant corporate milestone for the company and aligns with its strategy of securing district-scale precious metal assets in established mining jurisdictions.
The Gran Esperanza Project covers approximately 44,400 hectares of year-round accessible terrain in the Los Menucos District within the North Patagonian Massif. The property benefits from excellent infrastructure, situated approximately two kilometres from a paved highway with gentle topography and numerous secondary roads. The project is surrounded by major operators, including Southern Copper, and is located near the Calcatreu Project currently under development, highlighting the district's active exploration profile. More information about the company can be found at https://www.goldengooseresources.com.
Historical exploration at the site has identified greater than 10 kilometres of historically mapped low-sulfidation epithermal gold vein exposures, with veins averaging approximately 1-5 metres in apparent width. Previous work includes greater than 2,900 metres of trenching with 690 channel samples collected, with channel sample grades reported up to 2.0 metres at 24.0 g/t gold, demonstrating high-grade potential from surface. Historical surface sampling highlights include channel samples of 5.0 metres at 13.1 g/t gold, 1.3 metres at 11.5 g/t gold, and 3.0 metres at 4.4 g/t gold. Additional samples showed silver and copper mineralization, including 0.2 metres at 99.0 g/t silver and 2.8% copper, and 1.2 metres at 129.0 g/t silver and 3.5% copper.
Prior to executing the Definitive Agreement, Golden Goose completed comprehensive technical and legal due diligence, including a detailed review of historical data, surface geology, sampling records, land tenure, permitting status, and third-party technical reports. During a site visit in December 2025, the company collected four rock-chip samples from exposed mineralized veins. Three chip samples returned gold values above 2.0 g/t gold, including one sample grading 14.34 g/t gold, providing confirmation of the high-grade potential in the mineralized system.
Under the Definitive Agreement, Golden Goose may earn up to a 100% interest in the Gran Esperanza Project through a staged option consisting of cash payments and exploration expenditures. The total commitment amounts to $1,889,500 in cash payments and $2,599,000 in exploration expenditures. The project is subject to a 1.0% net smelter return royalty, of which Golden Goose has the right to purchase 0.5% for US$1.0 million. The company retains full flexibility to accelerate option payments or exploration expenditures at its discretion.
Upon exercising the First Option, Golden Goose and Valcheta will form a joint venture, with Golden Goose acting as operator and holding a 51% interest. Alternatively, the company may elect to proceed directly to a 90% ownership position by exercising the Second Option, thereby deferring joint venture formation. Upon exercising the Third Option, Golden Goose will hold a 100% undivided interest in the project.
Dustin Nanos, CEO of Golden Goose Resources, commented that signing the Definitive Agreement for Gran Esperanza represents an important milestone and transformative step for the company. He noted the project's favorable structural and geological setting, confirmation of numerous surface-exposed vein networks, excellent historical reported grades, and outstanding site access. The information collected to date positions Gran Esperanza as a compelling, drill-ready exploration project with the potential to rapidly deliver high-impact results.
The technical content of the announcement has been reviewed and approved by Marie-Pier Boivin, P.Geo, Senior Geologist at Dahrouge Geological Consulting Ltd., a consultant of the company, and a Qualified Person pursuant to National Instrument 43-101. During the December 2025 site visit, chip samples were collected along continuous sections perpendicular to the mapped veins, transferred into sample bags with unique sample ID tags, and sealed before being sent to ASI Laboratories in Mendoza, Argentina for analysis.
This acquisition positions Golden Goose Resources in a proven mining district with significant exploration upside. The Gran Esperanza Project's scale, accessibility, and historical data suggest potential for district-scale mineralization. The company's ability to earn 100% ownership through staged payments provides flexibility while minimizing upfront financial risk. For investors and industry observers, this move represents Golden Goose's commitment to building a portfolio of high-quality precious metal assets in jurisdictions with established mining infrastructure and geological potential.
